Good that this individual was identified and tested so quickly. Now to see if additional infections are found and if these stay connected to the first individual

During every past Ebola outbreak, the US has treated exposed citizens in state-of-the-art facilities. That has saved lives. This harsh action will risk the health and lives of Americans. It will also discourage health workers from assisting in the Ebola response.

Africa is standing united against the ongoing Bundibugyo Ebola Virus. Today, during the High-Level Ministerial Meeting, governments and partners announced approximately US$498.8 million in pledges and commitments to strengthen response efforts across affected and high-risk countries. This is a powerful demonstration of African solidarity, leadership, and collective responsibility in protecting our continent’s health security. As the outbreak evolves in a complex environment, trust, coordination, and rapid action remain essential to stopping transmission and saving lives. I thank our Member States, partners, and frontline responders for rising together at this critical moment for Africa’s Health Security. ------ L’Afrique reste unie face à l’épidémie en cours du virus Ebola Bundibugyo. Aujourd’hui, lors de la Réunion ministérielle de haut niveau, les gouvernements et partenaires ont annoncé environ 498,8 millions de dollars américains en promesses et engagements afin de renforcer les efforts de riposte dans les pays touchés et à haut risque. Ceci représente une démonstration forte de la solidarité africaine, du leadership et de la responsabilité collective pour protéger la sécurité sanitaire de notre continent. Alors que l’épidémie évolue dans un contexte complexe, la confiance, la coordination et une action rapide demeurent essentielles pour interrompre la transmission et sauver des vies. Je remercie nos États membres, partenaires et intervenants de première ligne de se mobiliser ensemble à ce moment crucial pour la sécurité sanitaire de l’Afrique. #AfricaResponds #DRC #Uganda

More unsettling news: 2 health care workers with uncertain exposure histories confirmed as #Ebola cases in Uganda. If they didn’t care for known cases, they were infected by undetected cases. That said, Uganda has been very effective in battling Ebola in the past.
🚨 @MinofHealthUG has confirmed 2 additional #Ebola cases, bringing the total number of confirmed cases in Uganda to 7. Particularly concerning is that these new cases are healthcare workers in Kampala and unclear if they cared for any of the other known cases. When health workers become infected, it raises concerns about healthcare-associated transmission, exposures in healthcare settings, and the potential for additional undetected contacts.

This is unsettling. The #Ebola confirmed and suspected case count is at 958 already in DRC, with 5 confirmed cases in Uganda. (Uganda doesn’t often disclose suspected case numbers.) This has all the makings of an ugly and protracted outbreak.
🚨 #EbolaRDC | Rapport de situation au 22 mai 2026 L’épidémie d’Ebola continue de faire l’objet d’un suivi renforcé par les autorités sanitaires dans les provinces touchées. 📍 3 provinces concernées : Ituri, Nord-Kivu et Sud-Kivu 📊 83 cas confirmés et 746 cas suspects cumulés ⚠️ 11 zones de santé touchées 📞 Numéro vert officiel gratuit : 151 Le respect des mesures de prévention et la vigilance collective demeurent essentiels pour limiter la propagation du virus. #StopEbola #PréventionEbola #SantéPublique #Com_MediasRDC

Ebola is no stranger in the Democratic Republic of the Congo, which has seen more than a dozen outbreaks since the virus was first identified there 50 years ago. But a new outbreak announced by the Ministry of Health has raised more red flags than usual. The ministry says there are already 246 suspected cases, including 80 deaths, in the remote province of Ituri, suggesting the virus spread widely before it was identified. The virus is a rare species called Ebola Bundibugyo, which standard field tests often miss, and for which no vaccines and therapeutics exist. scim.ag/42A38se

To the people of Tenerife, My name is Tedros, and I serve as the Director-General of the @WHO, the @UN agency responsible for global public health. It is not common for me to write directly to the people of a single community, but today I feel it is not only appropriate, it is necessary. I want to speak to you directly, not through press releases or technical briefings, but as one human being to another, because you deserve that. I know you are worried. I know that when you hear the word “outbreak” and watch a ship sail toward your shores, memories surface that none of us have fully put to rest. The pain of 2020 is still real, and I do not dismiss it for a single moment. But I need you to hear me clearly: this is not another COVID-19. the current public health risk from #hantavirus remains low. My colleagues and I have said this unequivocally, and I will say it again to you now. The virus aboard the MV Hondius is the Andes strain of hantavirus. It is serious. Three people have lost their lives, and our hearts go out to their families. The risk to you, living your daily life in Tenerife, is low. This is the WHO’s assessment, and we do not make it lightly. Right now, there are no symptomatic passengers on board. A WHO expert is on that ship. Medical supplies are in place. Spain’s authorities have prepared a careful, step-by-step plan: passengers will be ferried ashore at the industrial port of Granadilla, far from residential areas, in sealed, guarded vehicles, through a completely cordoned-off corridor, and repatriated directly to their home countries. You will not encounter them. Your families will not encounter them. I also want to say something else, something that goes beyond the science. I personally thanked Prime Minister @sanchezcastejon for #Spain’s decision to receive this ship. I called it an act of solidarity and moral duty. Because that is what it is. I want you to know that the WHO’s request to Spain was not made arbitrarily. It was made in full accordance with the International Health Regulations, the legally binding framework that defines the rights and obligations of countries and the WHO when responding to public health events of international concern. Under those rules, the nearest port with sufficient medical capacity must be identified to ensure the safety and dignity of those on board. Tenerife met that standard. Spain honoured it. Nearly 150 people from 23 countries have been at sea for weeks, some of them grieving, all of them frightened, all of them longing for home. Tenerife has been chosen because it has the medical capacity, the infrastructure, and the humanity to help them reach safety. And because I believe that so deeply, I will be there myself. I intend to travel to Tenerife to observe this operation firsthand, to stand alongside the health workers, port staff, and officials who are making it happen, and to personally pay my respects to an island that has responded to a difficult situation with grace, solidarity, and compassion. Your humanity deserves to be witnessed, not just acknowledged from a distance. As I have said many times: viruses do not care about politics, and they do not respect borders. The best immunity any of us has is solidarity. Tenerife is demonstrating that solidarity today. The ship’s captain, Jan Dobrogowski, crew and the company operating the vessel have shown exemplary collaboration at this challenging time. On behalf of the World Health Organization, and on behalf of those passengers and their families around the world, I thank the people of Tenerife and everyone else involved. Please take care of yourselves and of each other. Trust in the preparations that have been made. And know that the WHO stands with you, and with every person on that ship, every step of the way. With respect, care, and gratitude, Tedros
